        Hmm.  Well, I couldn't figure out how to do them (except the
service management thing, maybe).  Maybe I still don't understand cfengine
in spite of ongoing perusal of the documentation, although I like to think
I'm getting a bit of a feel for it.

        I'm guessing I'd be looking at something like:
-----
interfaces:
         "eth0:0" netmask=255.255.255.0 broadcast=ones
-----

        ...or maybe the mysterious netconfig command.  But that
interfaces section there doesn't let you specify an address.

        I note that you can specify "netconfig" in the action sequence.
Is there a corresponding undocumented "netconfig:" section of the config
file, or does it just figure this out from other info?

        Sorry, I left one out of the comment here -- I also wanted to have
cfengine figure out which filesystems exist, rather than me having to
specify them all in the cfengine config.  Is it still possible?

        Does this require editfiles, or is it possible another way?

        Thanks,
